Write a java program to create a jagged array of 2 rows with user defined column size and display all the values along with sum(rows). code example

Example 1: jagged array java

int[][] numbers = new int[7][];

// row 0 gets 5 columns
numbers[0] = new int[5];
// row 1 gets 11 columns
numbers[1] = new int[11];
// etc...

Example 2: how to get the length of a jagged array java

public static void main(String[] args) {

    int[][] foo = new int[][] {
        new int[] { 1, 2, 3 },
        new int[] { 1, 2, 3, 4},
    };

    System.out.println(foo.length); //2
    System.out.println(foo[0].length); //3
    System.out.println(foo[1].length); //4
}
